CHARLES O. MORLEY, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF TO JOHN J. MAY, OF BROOKLYN, NEW YORK.

ROTARY EJNGINE.

Application filed JulylO, 1901l To, all whom it may concern:

Be it known that 1, CHARLES O. MORLEY, a citizen of the United States, residing at Brooklyn, in the county of'Kings and State of New York, have invented certain new and useful Improvements in Rotary Engines, of whichf the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention gines in which there rotates in a cylindrical body a piston of less diameter provided with vanes or paddles operated upon by the steam I 5 or other vapor or fluid which is permitted to enter the barrel; and it has for its object to provide a simple, cheap, readily-constructed, and perfectlyoperating device by means whereof the vanes or paddles are projected from and retracted into the rotary'piston without the use of springs or other resilient elements while not permitting any leakage around the vanes and while yet the vanes will closely fit the inner periphery of the cyl-.

inder or barrel, a further object of the invention being to produce such "a device as will at all times operate perfectly and constantly; when rotated in either direction and in, which the friction of operation will be reduced to al 30 minimum. Y With these and other objects in viewmy invention consists in the novel construction and arrangement of parts hereinafter'full'y described and claimed.

In the accompanying drawings, forming part of this specification, in which like letters of reference designate corresponding parts in the several views, Figure 1 is a vertical section of a rotary engine embodying my inven- 0 tion, taken onthe line-a; w of Fig. '2, the piston and vanes being shown in elevation. Fig. 2 is a partial vertical section on the line 2 2 of Fig. 1; and'Fig. 3 is a section on the line 3 3 of Fig. 1, the piston, however, being shown with its slide-rod and vanes ranging horizontally instead of vertically, as in Fig. 1.

In the practice'of my invention I construct a casing A of cylindrical form and mount therein a cylindrical piston B of appreciably less diameter and contacting with the lower serial No. 67,761. (No model.)

wall or base of the cylinder and being arranged eccentrieally therein. In the center of the piston and extending throughout the which aremounted a plurality of rollers D. In the center of the piston and extending radially through the same and through the chamber'G is mounted a slide-rod E of a size to project slightly beyond either side of the piston. The said rod extends the full length of relates to that class of en-' the piston. Upon either projecting end of the slide-rod E, I pivotally mount vanes or blades F, corresponding in length to the cylinder and sectionally rectangular and formed with longitudinal beads or knuckles F, by means whereof they are pivotally mounted in the projecting ends of the slide-rod E. The size or extent of the projection of the slide-rod E, the knuckle F, and the vanes F is such that whether the slide-rod be equally or unequally extended on either side or whether but oneend thereof be extended and the other end with-its knuckle and vane be seated within'the piston the vanes will in any case lie in'close contact with the inner surface of the cylinder. This in consequence of the eccentricrelative position of the piston within the cylinder would not be possible' if the-cylinder were perfectly circular in section; but I cut away the cylinder at the points A and A uponthe lower inner portion thereof, so as to increase the runningspace for the vanes at these points, and this, together with the pivotal relation of the vanes to the slide-rod, accomplishes the object I refer to.

In Fig. 3 I have indicated in dotted lines at or about the points A and A what would be the inner periphery of the cylinder if it were in section a true circle, and this will show in general how these portions are cut out at A and A Around either end of the slide-rode E, somewhat within the edge ofthe piston, I mount two metallic packings'G', which are countersunk in the said piston and are pressed upon by the steam-pressure within the cylinder, which said steam enters through pipes H, leading from the outside of the piston to the outer faces of the packings G, so that length thereof is a chamber or recess 0, in

the varying steam-pressure exerts similarly varying pressure upon the packings to prevent leakage radially through the piston.

The piston is provided at either end with journals I, one of which is mounted in a plate or diskj, which closes one end of the cylinder when secured thereto by means of bolts J. The journal I is surrounded by an adjustable packing K, and the end thereof may form the shaft of the engine and receive a pulley or gear thereon. Upon the opposite end of the cylinder I secure a cylinder-head L, fastened by bolts L and adapted to receive the opposite journal I, the outer end of which rests in an adjustable packing M. Both of the journals I may be provided with a ball-race I.

In the top of the cylinder-head I screw the inlet-pipe N, which communicates with a port 0, formed in the cylinder-head L and communicating, by means of the port P, with a circular passage P in the collar 1, which is secured on the journal I and which is provided with the diametrically opposite port or orifice P which communicates with a fourway cock or valve Q, suitably mounted beneath the journal I and adapted to be rotated as desired. It is provided with two segmental passages Q and Q, the first of which communicates with the inwardly-directed passage S in the cylinder-head L, the said passage being extended through to the inside of the cylinder A in the form of a passage S. The passage Q communicates with the exhaust-pipe R, secured in the bottom of the cylinder-head, and connects it to a similar passages on the opposite or right-hand side of the cylinder-head, which passage S communicates, through a passage S, to and with the cylinder A, upon the opposite side to which steam is admitted through the firstmentioned passage S. The valve Q has a stufling-box Q mounted around its stem and may be turned either by the hand or by any suitable implement. Above the passages S are branch passages T, leading therefrom into the cylinder and governed by valves T.

The operation of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings, and the advantages resultant from the use thereof will be manifest to all who are conversant with devices of this character.

Steam is admitted to the engine through the inlet N and passes through the port 0, the port P, the passage P, the ports P and Q, and passages S and S into the cylinder and operates against the vane or blade F, thereby rotating the piston. As soon as the piston has begun to move its journal I carries the collar P around with it and shuts off the port P and prevents further steam from entering the cylinder until the piston has made a semirevolution, whereupon the port P is uppermost and the port P is undermost, and

steam again enters. As the piston revolves its slide-rod is forced outwardlyin the direction of the vane, against which the steam presses and withdraws or retracts the opposite vane, which gradually enters into the piston. Thus the vane borne against by the steam is always maintained in contact with the inner periphery of the cylinder. By reason of the form of such cylinder and of the pivoting of the vanes a perfect contact will be maintained between the vane and the cylinder, so that there is no leakage. The exhaust-steam escapes through the valve T of the passage T, which leads to the exhaustpipe B. When it is desired to reverse the direction of the engine, it is but necessary to turn the four-way cook or valve Q a quarter of a revolution, thereby connecting theirighthand passage S with the steam-inlet N and connecting the left-hand passage S with the exhaust, whereupon the engine will run in reverse direction without change of mechanism or position of the parts.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

In a rotary engine, a cylindrical casing, a cylindrical and rotatable piston mounted eccentrically therein and in contact with the bottom wall thereof, a slide member mounted radially in said piston longitudinally thereof, and provided at the opposite sides of said piston with pivoted vanes, a collar connected with one end of said piston, and communicating passages formed in the casing and in the collar, a steam-inlet in communication with the passages in the collar, a four-way cock controlling the communication between the passages in the casing, and the passages in the collar, and an exhaust and means for controlling the same.
